UNITED STATES PATENT OFFICE.

JOHN DARLING, OF GLASGOW, COUNTY OF LANARK, SCOTLAND.

NEEDLE-TH READING DEVICE.

SPECIFICATION forming part of Letters Patent No. 275,157, dated April 3, 1883.

Application filed December 1, 1882. (No model.) Patented in England July 29, 1882, No. 3,599.

To all whom it may concern:

Be it known that I, JOHN DARLING, of Glasgow, in the county of Lanark, Scotland, have 1882,) of which the following is a specification.

This invention, which relates to improvements in needle-threading devices, consists in the construction and application of the same for the purposes hereinafter more particularly described.

Figure l of the accompanying sheet of drawin gs represents a side elevation of a bobbin fitted with a needle-threadin g device constructed according to my present invention. Fig.2 represents a plan of the same. Fig. 3 represents a section through the same. Fig. 4represents a side elevation of areceptacle for a thread-bobbin with a needle-threading device attached thereto, constructed according to my present invention. Fig. 5 represents a plan of the same. Fig. 6 represents a section through the same. Fig. 7 represents, on an enlarged scale, aside elevation of a thimble fitted with a needle-threading device constructed according to my present invention. Fig. 8 represents a section through the same. Fig. 9 represents in section an enlarged detail view of the needlethreading device constituting my present invention.

Within the hollow part of the bobbin A, I tightly fit a metal tube, B. To the inner side of the tube B, I secure the needle-threading device, which consists in the back or guide 0,

the hook (I, and the spring-piece e. In threading a needle it is first drawn across the guide 0 (whose upper edge is notched for this purpose) until the eye of the needle passes over the hook (I and the forward part of the same passes down and is retained within the springpiece e. The thread is then passed beneath the hook (I, which projects through the eye of the needle, and the needle is then withdrawn, when the thread, still retained by the hook at, is drawn through the needle-eye.

Upon the cover D, Figs. 4, 5, and 6, of the receptacle E, I fit a needle-threading device, which is in general similar to that hereinbefore described with reference to Figs. 1, 2, and 3. The back or guide f of this device is formed by the part out from the opening 9, through which pass the hook h and spring-piece i, which are both secured to the under side of the cover D, as more clearly shown in Fig. 6. Through the side of the receptacle E is drilled the hole j, for the passage therethrough of the thread contained therein upon the bobbin 70. As a modification of my said invention, the back or guide fhas or may have formed in it an oblong hole, which, when the needle-eye is passed through it, places it in the necessary position for passing over the hook h.

The thimble represented at Figs. 7 and 8 has fitted on its outer side a needle-threadin g device, which is formed of the spring-piece m, secured to the thimble at its bow or closed end adjacent to the rim of the same. The hook n is secured to the side of the thimble, between the ends of the spring-piece m. In threading a needle in this device it is pressed down between the spring-piece we, so that the eye of the needle passes over the hook at, which is then treated in a manner similar to that hereinbefore described.

I claim -1. A needle-threading device comprising a guide, a hook, and a spring, being constructed and relatively arranged substantially as shown and described.

2. The combination of a bobbin or sewing utensil with a needle-threading device comprising a guide, a hook, and a spring, arranged relative to each other in the order named, substantially as described.

3. In a needle-threader, the combination of the guide 0, spring 0, and hook d, substantially as set forth.

4. The combination of the cover D, having the opening 9, the guide f, formed from the cover, the spring, and hook, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN DARLING.
